测试 19c asm flex 的 功能： 在节点1上面执行 srvctl stop asm -node test-rac19c-01 -stopoption abort -force 报错 因为 ora.asm_listener.type 是asm监听的主节点，节点1为主节点，主节点无法关闭 [grid@test-rac19c-01 ~]$ srvctl stop asm -node test-rac19c-01 -stopoption abort -force PRCR-1214 : failed to stop resource group ora.asmgroup PRCR-1214 : failed to stop resource group ora.asmgroup CRS-2670: Unable to start/relocate 'ora.asm_listener.type' because 'ora.asm' has a stop-time 'hard' dependency on it CRS-5027: The ASM instance on node "test-rac19c-01" cannot be stopped because it is currently being used by Cluster Ready Services.
